    NOTE:

    The number of DIMMs corresponding to a memory channel varies depending on the server model.

You can obtain the CPU socket number and channel number corresponding to a DIMM from the server user guide. For example, if you use a 2488 V5 server, see Components > DIMM Slot Locations in the 2488 V5 Server V100R005 User Guide.

arg3

Error code of the alarm.

Impact on the System

The server performance is affected.

Possible Causes

  • The DIMMs installed are not compatible with the CPU.
  • The DIMM layout does not comply with the configuration rules.

Procedure

  1. Power off the server and check the models of the DIMMs for which the alarm is generated.
  2. Use the Huawei Server Compatibility Checker to check whether the DIMM models are compatible with the server.

    • If yes, go to 3.

    • If no, go to 5.

  3. Check whether the DIMMs are installed in correct slots.

    • If yes, go to 6.

    • If no, go to 4.

    For details about DIMM installation positions, see the user guide of the server you use.

  4. Install the DIMMs in correct slots. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 6.

  5. Replace the DIMMs with compatible ones and power on the server. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 6.

    For details about how to replace a DIMM, see the user guide of the server you use.
